Independent Development of Gas-Solid Closure Models Used in Industrial Reactors ——Summary of applicability of gas-solid closure models
上海交通大学Pelab研究组长期从事反应器工程研究与开发工作。提出了反应机理的识别方法，建立了基于“分组矩+随机”的“可视化”动力学模型；自主开发了多个关键反应器封闭模型，以建立的动力学模型为源项耦合自主开发的封闭方程，建立了考虑非均匀结构的多尺度粗网格计算流体动力学模型；上述模型及模拟结果指导发明了“斜角”气液搅拌浆与气固分支内构件等强化多相传递的反应器构件，在多家大型企业中实现了多类大型工业反应器的改造、优化与设计。
Pelab research group of Shanghai Jiao Tong University has been engaged in chemical reactor engineering research and development for a long time. We developed a method of moments based deterministic model and a kinetic Monte Carlo-based stochastic model for identification of the reaction mechanism and visualization of the reaction process. Moreover, several closure models for key chemical reactors were developed independently. A multiscale coarse-grid computational fluid dynamics model considering the effect of inhomogeneous structures was thereby established by coupling the developed closure equations with the developed kinetic model as the source term. The above models and simulation results have led to the invention of the reactor components (e.g., the beveled impellers for gas-liquid slurry systems and the branched internal components for gas-solid systems) to enhance the multiphase transport process, which have realized the upgrading, optimization, and design of several types of industrial reactors in many large enterprises.
就本组自主开发的针对气-固两相流体系的相间封闭及修正模型/方程，近期有众多的国内外课题组与本组来信索取有关资料及开源代码等。为方便学术交流并共同推进相关研究，我们将首先总结自主开发的气固两相流封闭模型，后续视需求总结反应机理识别与动力学建模方法（含源代码）。通过本次根据同行需求提供的总结，期待更多同行开展相关模型开发、评估及测试，完善两相流模型，推动反应器新研究范式的发展。
Recently, some domestic and foreign research groups have written to request the relevant information and open-source code regarding the interphase closure and the modification model for gas-solid flows developed by our group. In order to facilitate academic exchanges and jointly promote relevant research, we will first summarize the closure model of gas-solid flows independently developed, and then summarize the reaction mechanism identification and kinetic modeling methods (source code included). It is hoped that more peers to carry out development, evaluation and testing of relevant models due to the summary provided according to the requests of the peers. It is also hopeful to further improve the two-phase flow model and to promote the development of new reactor research paradigm.
